TO ALL WHOM l'l MAY CONCERN:

Be it known that I, SABIUEL SYKES, ot' Chippewa Falls, in the county oi-Chippewa, and State of Wisconsin, have invented a new and use-fnlImprovement in Dogs for Drawing Saw-Logsg and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same,ret'erenee being had to the accompanying drawings, forming part of thisspecification.

This improvement relates to the manner in which the dog which is driveninto a sawdog 0r other logs for the purpose of a hold-fast isformed, andthe invention consists in elongating the common dog and turning up theelongated portion, whereby the dog is easily detached from the log.

Figure 1 represents a vertical longitudinal section of the dog with myimprovement attached to a saw-log.

Figure 2 is a top or plan view of the same.

Similar letters of reference indicate like parts. V

A represents the log; B is the dog with my improvement; C represents thedevice; D the eye and belt by which the clevis is attached to the dog; Eis the chain attached to the clevis to which the team Vis hitched. Thedog in common use terminates where the elevis is attached, and in usingit great diiculty is found in getting it out of the log unless a bar isat hand for the purpose. It has to be pried out, which is frequently atroublesome operation. My improvement is in adding the part marked F,which stands as represented in the drawing, when the dog is in the log.New, to detach it in :1n instant with a mallet or lever, all that isnecessary to be done is to strike the part F, which I have added, asmart blow, and the thing is done. F, with the horizontal part ofthedog, forms a bent lever, whose fulcrum is at the point a, on the log,and a' blow on the end of F has suheient power to withdraw the bit ofthe dog at one-c. G represents the bit.

This simple device saves much valuable time in the handling of logs; andit will at o'nce he understood and appreciated by all who are acquaintedwith the subject.

W'hat I claim as new, and desire to secure by Letters Patent, is

The partF, forming with the body ofthe dog a bent lever, as and for thepurposes herein shown and described.

SAMUEL SYKES.
